Phenolic air duct is a non-metallic composite air duct. The middle layer is phenolic foam, and the inner and outer layers are embossed aluminum foil composite. Phenolic formaldehyde composite air duct has the advantages of good insulation, good noise reduction, light weight, long service life, convenient installation, hygiene, and aesthetics, and can be widely used in industrial and civil buildings; However, it also has the disadvantage of not being used in clean air conditioning systems, acid-base air conditioning systems, and high-pressure systems. Let’s learn about the advantages and disadvantages of phenolic composite air ducts together.
1、 What material is phenolic air duct?
Phenolic air duct, also known as phenolic composite air duct, is a composite air duct made of phenolic foam plastic, aluminum and other materials. Generally, the middle layer is phenolic foam, and the inner and outer layers are made of embossed aluminum foil. It is widely used in various industrial and civil buildings and other places with special requirements.
2、 What are the advantages and disadvantages of phenolic composite air ducts?
As a type of composite air duct, phenolic air duct has both advantages and disadvantages. Below, we will introduce it to you:
1. The advantages of phenolic composite air ducts
(1) Good insulation: The thermal conductivity of phenolic composite air ducts is 0.020~0.025W/(m · k), which is much smaller than that of galvanized steel sheet air ducts and fiberglass air ducts, and the heat dissipation loss is less than 2%.
(2) Good noise elimination performance: the interlayer of the phenolic aluminum foil composite air duct wall is a porous phenolic foam material board which is interconnected, with good noise elimination performance.
(3) Lightweight: The phenolic aluminum foil composite air duct is lightweight, about 1.4kg/㎡, which can greatly reduce the load on the building and is beneficial for the installation of the air duct.
(4) Long service life: The service life of phenolic aluminum foil composite air ducts is at least 20 years or more. In addition, the reuse rate of phenolic aluminum foil composite air ducts can reach 60% to 80%.
(5) Easy installation: The phenolic aluminum foil composite air duct is lightweight, and installation is more convenient and fast than traditional air ducts. When lifting air ducts, simple hangers are required, with fewer quantities and almost no need for machinery.
(6) Hygiene: The surface of the phenolic aluminum foil composite air duct is sealed with aluminum foil, ensuring the hygiene of the conveying medium, avoiding secondary pollution, and the inner layer is free of condensation water and rust.
(7) Aesthetics: Phenolic aluminum foil composite air ducts can be made in various colors, which are beautiful and especially suitable for surface decoration.
(8) Wide application range: Phenolic aluminum foil composite air duct can be widely used in industrial and civil buildings, hotels, hospitals, office buildings, and other special requirements places.
